iPhone 8 Plus and iPhone X: New rear-facing, dual-camera designs

The iPhone 8 Plus and iPhone X have a dual-lens design, with wide and telephoto lenses, while the iPhone 8 just gets the one.

Apple says the back-illuminated sensors have an "all-new" design, with deeper pixels and a new colour filter, which "enable wider dynamic range and better colour saturation".

The sensors are also said to absorb a whopping 83% more light than the sensor inside the iPhone 7, which is very encouraging for those frequently shooting in low light.

On the iPhone 8 Plus, the wideangle lens has an aperture of f/1.8 while the telephoto optic has an f/2.8, and optical image stabilisation is on board too.

This is also true of the cameras inside the iPhone X, although the telephoto lens has a wider f/2.4 aperture.

iPhone 8, iPhone 8 Plus and iPhone X: Better video shooting modes

Not only do the models offer 4K video at 24, 30 and 60fps, but you can also record Full HD footage at frame rates up to 240fps for ultra-slow-motion playback.

Normal HD footage is recorded at either 30fps or 60fps, although you can also call upon a 720p option at 30fps.

Video stabilisation is also said to be improved from the iPhone 7. Apple didn't go into any details as to how, but hopefully we'll see better stability when moving around.

You can also take 8MP still images when recording 4K videos with all three models.

iPhone 8, iPhone 8 Plus and iPhone X: Displays

While the iPhone 8 will get a new 4.7in display, the iPhone 8 Plus will see a 5.5in version.

The former has a 1334x750pixel resolution at 326ppi, while the latter has a Full HD (1920x1080) display at 401ppi.

Each is a new Retina Display, with a 'cinema-wide" colour gamut, although it's the display on the iPhone X that sounds particularly tasty.

Measuring 5.8in in size, it's a Super Retina OLED display that packs 2436x1125 pixels and goes from edge to edge. This resolution and size give it a super-high density of 458ppi for extra clarity.

iPhone X: TrueDepth Camera system

The iPhone X sports a new TrueDepth camera system, which is the front-facing camera. Not only is this responsible for helping you snap selfies, but it also enables Face ID.

This unit comprises a front camera, ambient light sensor, infrared camera, flood illuminator, proximity sensor and a dot projector, as well as a speaker and microphone.

And, with all of this on board, the camera is able to be unlocked just by sensing your face – just as well, as there's no Home button anymore.

The iPhone 8 and iPhone 8 Plus, meanwhile, sport 7MP front-facing cameras, with back-illuminated sensors and an f/2.2 aperture in each lens.

iPhone 8 Plus and iPhone X: Portrait modes

The iPhone 8 Plus and iPhone X models sport a new Portrait and Portrait Lighting modes, which use real-time analysis to help you capture a better portrait. This works on both the front and rear cameras.

Apple says this is still in beta, but that it will ship with both models from the start.

iPhone 8, iPhone 8 Plus and iPhone X: AR functionality

As was strongly rumoured before today's launch, the cameras inside the new iPhone 8 Plus and iPhone X have been calibrated for Augmented Reality (AR).
